**WARNING** I usually print in ABS this hasn't been tested in PLA or PETG. If it work let me know and I will update this.
I really liked the Joint Locker from Another Room and saw the video from Slant3D about the design and manufacturing of their product.
I've seen a couple of people who have made “Homages” and thought I would take a stab. and have a bit better grip in the lighter with something similar to the Grip Fins the Slant 3D came up with.
I have included .step files if you need to move some walls around or add a sick logo.
